Weight - Class 2

This article is based totally on weight, which is a captivating concept that surrounds us every day. In this text, we can set out on an adventure to explore the idea of weight, apprehend its importance and discover how we measure it

What is Weight?

Weight is a unit of measurement for how heavy something or someone is. Depending on an object's weight, we can divide it into two categories: heavy and light.

If an object has more weight, then it is called heavy. Elephants, lions, tigers, sharks, whales, eagles, ostriches, cylinders, buildings, towers, etc are some heavy weight objects.

If a body has less weight, then it is called light. Ants, bees, flies, mosquitoes, papers, feathers, cotton, hair, etc are light weight objects.

In the given figure, a cat is lighter than a tiger. Thus, a cat is a light weight and a tiger is a heavy weight.

Example of Light weight and heavy weight

When you compare a tiger with a blue whale then we can see a tiger is lighter than a blue whale.

Example of Heavy weight and light weight

Measuring Weights

The weight is measured using weighing balance and weighing scales, shown below:

Devices used for measuring weight

Let's understand how weighing balance works. A weighing balance has two pans in it. The pan holding the heavier goods slides down and the pan holding the lighter items rises.

Weight measurement

Both pans rest at the same level if their weights are equal.

Units of Weight

The units in which we measure Weight are kilograms, grams, ounces, pounds and many more.

Conversion of One Weight to Another

1 kilogram = 1000 grams
1 pound = 16 ounces

Symbols for units of weight

The symbol for kilogram is kg.
The symbol for gram is g.
The symbol for ounce is oz
.The symbol for pounds is lbs.

Example: What is the weight of the vegetable basket in kilograms?

What is the weight of the vegetable basket in kilograms

a) 5 kg
b) 50 kg
c) 500 kg
d) 5000 kg

Answer: a) 5 kg

Explanation: Weight of the vegetable basket in grams (shown on the weighing machine) = 5kg

Example: A watermelon is six times as heavy as a melon. If the weight of the melon is 600 g, what is the weight of the watermelon?

what is the weight of the watermelon

a) 2 kg 500 g
b) 3 kg 400 g
c) 3 kg 500 g
d) 3 kg 600 g

Answer: d) 3 kg 600 g

Explanation: Weight of the melon = 600 g
From the given problem, a watermelon is six times as heavy as a melon.
Weight of the watermelon = 6 x weight of melon

= 6 x 600
= 3600 g
= 3000 g + 600 g
= 3 kg + 600 g

Weight of the watermelon in kilograms and grams = 3 kg 600 g
